Rare-earth magnets are strong, permanent magnets made from alloys of rare earth elements.they are substantially stronger than ferrite or alnico magnets. The magnetic field typically produced by rare-earth magnets can be in excess of 1.2 teslas. They offer many advantages, and have drastically increased flux compared to traditional magnets with comparable volumes. It consists of rare earth magnet particles and a rare earth oxide being present between them. They are made from rare-earth elements
